Would the MSI GeForce GTX 660 Ti Power Edition be compatible with the ASUS P8H61-MX motherboard? Please answer, I cant find this anywhere.
You'll be glad to know that the MSI GeForce GTX 660 Ti Power Edition will work on your ASUS P8H61-MX motherboard. Your motherboard has a PCI-Express x16 slot, which will house the Power Edition GPU quite nicely.
It'll mainly come down to your power supply unit (PSU), whether it has enough power to properly power your GPU - but the GTX 660 Ti PE doesn't chew through that much power anyway, so you should be fine. I hope this has helped you!
